In residential construction, the height of a typical storey can vary depending on building codes and design preferences. However, 12 feet (4 meters) has become a standard measurement that accommodates both the living space requirements and the necessary clearance for airflow, fixtures, and potential design features. This height allows for practical design choices, providing ample room for lighting fixtures and ceilings while also maintaining structural integrity.

While other options may represent heights that are used in various contexts or building types, 12 feet generally represents the average expectation for a residential storey in many constructions, particularly when considering factors such as insulation, aesthetics, and code compliance. Thus, this choice aligns most closely with industry standards for modern residential buildings.
